Why does a teaspoon full of sugar makes hiccups go away?

There are over 25 different factors that cause synchronous diaphragmatic flutter (or hiccups) from electrolyte imbalance, eating too fast, heartburn to even chemotherapy but can be cured almost instantaneously by dissolving a teaspoon of sugar in your mouth and swallowing it all together. What exactly makes sugar a cure for something beyond annoying? Is it the molecular structure? It is the properties of it being a solute? What the hell is it?...Oh and don't be a dumb f**k when answering this.
